New Defender's Study Bible Notes
23:19 he should repent. Some take this assertion as contradictory to such passages as Genesis 6:6: “It repented the LORD that He had made man on the earth.” It is not really God who “repents”–that is, “changes His mind”–but man. When men change, God must revise His attitude and behavior toward them, precisely because He is Himself unchangeable. He must continue unchanged in His own righteous character and standards, and thus may appear outwardly to “repent” in order not to repent inwardly.
